Patented D131. '7, 1922.

1920.1serialuaseaea 'Y frame, said4 standard being provided atits upper en'd with a'block 16 provided with a groove 17 v,in which the rib 13 is adapted 'to engage, tliemember 15 thereby serving to support the tube 12 at itsrearward end, the forward endof the tube 12'resting upon the table 2Q which is usually present in tack machines. 'Adjacent the forward end Aofthe tube` 12 is provided a standard 17 which passesadjacent one sideof the'tube 12 and is provided :at its upper end withA an arcuate spring 19 which is y adapted tofengage the upper surface of the Ytube12. As the tube 12 oscillates, thev fo'rwa'rdend thereof, which istapered,l engages thetfable 20. and raises upwardly, the sprinlg19 serving to resist` thefupwardimovement 'of this end of the tube!" Upon lthe' complete` oscillation, the spring 19 restor es the tube to its operating position uponthe `t'able20. The forward end ofthe tub`ef"1j2`is provided with a tongue 20, which projectsfbeyond the main body thereof,the tongue 20 being f formed cen trallyA longitudinally of the tube 12 so* as to' eiigagei'the* strip "of metal 'which -fpass'es throughhe" slot formed longitudinally of the tube 12. l" As shown in Fi.g.'1,the rearward end of' the tubef12 is formedflaring, asfat 22,"so Vtha-tan insertion ofthe .metalblank rfromv whichtl'iev tube i'sito b'ejmade may bereadily'had in the slot 2lformed in thek tube; I AAdj acent the rearward end ofthe tube i's'p'ositioned a circumferential rib 24 which is? provided with teeth, the member 24 being rigidly fattached to the tube 12. Embracingthe-tube12 is a U-shaped member'or stirrup`25', the legs of which are joined together by lan arcuate bar 26 'which is adaptedto mesh with the teeth formed on the member '261. Secured'to rthe -bight of the member 25, vcentrally thereof, is one arm 27 @f a bell'crank, the opposite arm 28 of which is securedto the usual reciprocating rod ordinarily operated by the tack machine to oscillate the guide tube. The bell crank is pivoted vupon the' standard or support 30 Secured to the' table or floor,as the case may y be. p Itis evident that ,upon reciprocation of ALs Ythe. member 2 5' reciprocates, the teeth on the member 26, engaging with the teeth on the' member-24, causes the' tube 12 to oscillate, thereby presenting, alternately, the opg secured to Athe ioor or other rksupporting yp'osite-sides ofthe strip 23 in engagement K with the table so as to provide `for `the proper angle of the cutmlade'bytheilenife of the tack machine on the strip 23. Mount-V ed upon the me1nber12, adjacerit'its 'rearward end, is a housing 31 through Whloh projects, adjacent its -iipperiend, ashtftBQ.

4the housing, intermediatevlthe vvalflV thereof and the tube 12, atjopposite sides o: f said tube, are bearings'34,in4 which theshaft. 3 2. is journald. Mounted in `a slot35 :formed in the tube 12,A ,and rigi-dlyattachedto Ythe.

l s hatt32,is a roller35. `Adjacent the lower jected therethrough, said shaft 36being journaled ,in bearings 37 f similarly ,formed and similarly positioned to the-bearings Thehousing 31 `is provided onf it s,inner surface atfthe point where theshaft 36fpasses through, with a f shoulderr similarly `'eenstructed 'to the lshoulder` 33. Mounted in Va slot formed in the tube 12 fandgpositioned .z upon the shaft36 ,is1 a roller 3 8 avhichrxisgdee signed` to (3o-operate with the roller 3.5 for engaging and feeding forward tack blank 23 inserted in -theslot 21. .Rigidly attached to the shaft 3 2, exterior tothe housing '31,l `is ia gear Wheel 351,y which v-is movement ofthe bearings 'in whichthegshalit adapted to mesh With a gear WheelOwhich is rigidly attached to .theshaft 36and posi-` tioned exteriorly of the housing 31. To the opposite end of the shaft 36 exteriorlyof thehousinof` 31, is rigidly attached fa bevel gear 41. (diving to the fact that'the opening through'the housing *is largerthan the shafts 32 and 36,it is evident that the rollers 35 and'38 are movable relatively to each other. Provided upon the supper surface of the housing 31 fare arranged' spring'mem bers'42 and 43, which are adapted to engage the upper surface of the bearings in which the shafts 32 and `36 are mounted so asto press the rollers 35 and 38 yinto closerelaf tion `with each other, suitable slots being provided in theupperuvallof the housing 31 for fpassa'ge of the bearings therethrough upon spreading .apartof the rollers 35-and 38. Similarly, the lower wall ofthe housing 31A is `provided with-slotsth'ough 'which t'hebearings in rwhich =shaft. 36 isi` mounted may project, and similar 'springs'44fand-45 are .'-provide'd for vresisting the outward 36 -is mounted, so as to; maintain the rollers 3,5 and 38 in close relation toeacli` other.

The Apurpose of movably 1monnting, Ythese v rollersin themanner indicated,y is to provide for 1 a spreading-apartfof thehsame should any inequalities in the -,mateiial 2:23 bexpresent ras. Athe same .passes thoeghfthe IQllerS. Rgidly mounted `upon the Shaft 36,

exterior of the housing 31, is a bevel gear 41 V`Lwhielfi'is adapted tojmesh with a bevel gear 46 which is rigidly attached to one end of a Vshaft 47 'journaled in bearings 48 and 49 mounted upon the housing 31 and 31', the

designed Ifor cooperation with a roller 53 mounted upon a .shaft 53 which projects the housingflf and isv journaled in bearings sucha'sfare present inthe'housing 31. j Similar springs 56 an d` ft' 5v vare provided u onthe lower and upper Walls,.respect1vely, el.) the housing `31' for lthe' same [purpose as tlie ,.springs already described as 4attached y toV the-housing `31. Mounted upon the shaft 53,1exteri or.of the housing31, vis a pimon 57 ada vted tomesh with a pinion 58 which isrigi ly attached tothe shaft 52. Mounted upon the opposite 'end of the shaft 52 is a gearwheel 59, which is`adapted to `mesh* v` withvfagear. 60 which is rigidly attachedto a ratchet wheel 61. Saidratchet Wheel 1s loosely mounted upony a shaft' 62 which pro` jects 'through the housing 31. Mounted upofrnthe P Ilaftform or `table to which the standard`15 is secured, are vsuitable posts 63 and 64said posts bei-ngpositioned at opposite lsides of thetube'12. Loosely mounted uponthe shaft62, exteriorly of the ratchet Wheelv l61,V is an arm `65 bearing at opposite ends o'ppositely directed pawls 66 and 67 which'are adapted to engage the teeth on the ratchet Wheel 61. Projecting outwardly from nthe. member 65, adjacent its opposite ends, are suitable stops 68` and 69 so ypositioned thatuponoscillation of the tube 12, one of the stops 69 engages the upright 64 whilethe other stopV 68 Vengages the upri ht 63. f

n operation, upon reciprocating'tlie rod 29, oscillation ofthe tube'takcs place, as already explained. Vhen oscillation takes placewhile the machine 4is in the position shown in Fig. 4, the outwardly extending post orstop 68 Willengage the member 63 and cause a movement of the arm 65 relatively'to the shaft 62. This will cause a rotation of the ratchet wheel 61 for a predetermined distance, depending upon the distance v the tube 12 oscillates after the member 68 has. engaged the post. This will causea rotation of 'thefgear 60 and a consequentrotation of thev rollers is brought -about. In-this manner, theftack blankis of rollers contained within the housing '3l are merely auxiliary krollers for the purpose of 'feeding an auxiliary strip of metal so that the two strips of metal may be contained within the tube at the saine time. Rigidly attached to the shaft 62. is an arm 71, to one end of which is attached one end of a spiral spring 73, the opposite end being attached adjacent .the end of the arm 65 to which the pawl. 66 is secured. .To the opposite end of the member 71 is att-ached one end of-a spiral spring 72, the opposite end of which is att-ached to the arm 65 adjacent the end to which the pawl 67 is secured. The purposev of the springs 73 and 72 is to return the arm 65 to its former position relatively to the shaft 62 after each engagement with the stops 63 or 611-.

the member' 1 and preferably made integral therewith, a stop 72, which is adapted to limit the backward movement of the arm As shown i Fig. 7 there is mounted upon ,65: in response to the strain of the springTQ.

- iMounted uponthe arm 7.1 is asimilar stop 7 3', which 'is adapted to limit the backward movement of the arm in response `to the strainvof the spring 7 3.

In'Fig-8, I have shown in which the arm. 65 and the stops 63 and 64e and the necessaryrco-operating. paitsare dispensed with. Mounted upon a pedestal 711qisan armv 75, ywhich extendsV to. one sidey of the tube 12 and is provi-ded at yits end with a tubular portion 76 inv which is slid.- ably positioned a stem78 having a pawl 7 9 at one end' thereof, adapted. toV engage `the teeth of the ratchet wheel 61. The member 7,6. ispi'ovidedadjacent its upper venfil'ivith a recessain' which isl seated a spiral spring` whichissleeved upon the` upper end of the member 78. .One end ofthe spiral springV 82 is adapted to engage the base of the recess 80,'whereas'the other end is adapted toengage the under surface of a cap 81Y which is secured to the stem 78. The oppo site end of the stein 7 8; is provided with a collar 83.7which limits its upward movement relatively to the member 76. The construc tion is such that'upon oscillating` the tube 12. the ratchet 61 is brought into engagement with the pawl 79 and a consequent ro.V

M modified form .of the actuating device of the ratchet wheel,

respectively, with inwardly t'urnediportions j 86 `and 87 whichare adapted to engage the tack blank 23 at opposite sides thereof, so as to retain the same rigid while the knife is making the cutting stroke. These members 8aand 85V are usually formed 'of some spring metal, and are merely shown here for the purpose of illustration, the same forming no part of this invention.

Vilhile' I have illustrated and described the preferred form of construction for carrying my inventioninto effect, this is capable of variation and modification without departing from the spirit of the invention. l,`

therefore, do not wish to be limited to the precise details of Vconstruction set forth, but desii'e to avail myself of such variations and modifications as come within the scopeV of the appended claims. o o
